TXB0104RUTR

Translators, Level Shifters Overview

The TXB0104RUTR is a four-channel bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes two separate configurable power-supply rails to facilitate universal low-voltage translation between various logic families. The A port accepts supply voltages from 1.2 V to 3.6 V, while the B port supports 1.65 V to 5.5 V, ensuring VCCA does not exceed VCCB. Key electrical parameters include a maximum data rate of 100 Mb/s and a propagation delay of 7.4 ns. The device operates within a temperature range of -40°C to +85°C and features ±15 kV ESD protection on the B port.

Translators, Level Shifters Feature Summary

• Features automatic direction sensing for seamless bidirectional signal translation without requiring explicit direction control signals.
• Incorporates Ioff circuitry that disables outputs during power-down to prevent damaging current backflow through the device.
• Provides robust electrostatic discharge protection exceeding JESD standards with ±15 kV human model protection on the B port.

Translators, Level Shifters Applications

• Bidirectional level shifting in mobile devices such as smartphones and tablets
• Voltage translation for computer peripherals and desktop systems
• Audio interface connections including headphone circuits

Translators, Level Shifters Procurement Notes

Verify the specific package marking and manufacturer date code upon receipt to ensure authenticity. Confirm that the received component matches the TXB0104RUTR designation exactly, as similar suffixes may indicate different packages or automotive grades. Check for physical damage to the UQFN-12 leads before soldering. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to maintain reliability during assembly.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring automatic direction sensing for bidirectional communication between mixed-voltage domains. It is suitable for applications where VCCA must be lower than or equal to VCCB, supporting transitions between 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V nodes. Consider the UQFN-12 package constraints and thermal requirements for high-density PCB layouts.

Translators, Level Shifters Part Context

This part belongs to the TXB0104 series of voltage-level translators from Texas Instruments. It shares functional similarities with other members like the TXB0104RGYRG4 but differs in packaging. The RUTR suffix specifically denotes the UQFN-12 surface-mount package configuration, distinguishing it from TSSOP or QFN variants within the same logical family.

Translators, Level Shifters FAQ

What is the relationship between VCCA and VCCB?

VCCA must not exceed VCCB. The A port tracks voltages from 1.2 V to 3.6 V, while the B port tracks 1.65 V to 5.5 V.

How does the device handle partial power-down scenarios?

The integrated Ioff circuitry automatically disables the outputs when the device is powered down, preventing destructive current backflow through the input or output pins.
